|100 * [(370 - 365)/365] = 4.1%.

|Yes, there is one fast method.
We can visibly calculate the difference between two value i.e. difference of (15) coming only in two different years.
And when we divide the difference with the previous year value means the year which have larger value in denominator will give less value.
Ex- 15/385, 15/370.
Hope this will help.
